1 Overview
This Functional Specification defines communication with LV-NI02 for LV-7575.
Supporting Farmware Ver. 1.x of the projector.
Commands in this document are to communicate with LV-NI02, but most commands are used to
control a projector remotely from a computer with RS-232C. Therefore commands in this
document are defined as Expand Serial Commands.
2 Serial Interface Specification
2.1 Transfer Specification
Item Specification
Synchronous System Asynchronous
Transmission Speed 9600 / 19200
Data Length 8 bits
Parity N/A
Stop Bit 1
Flow Control N/A
Note1) Transmission Speed: initial setting value is 19200
Note2) Transmission Speed can be changed in Service mode.
2.2 Connection
Dedicated serial cables that come with the projector must be used for the connection between a
computer and a projector.
PC Projector
COM 1 Control Port
(D-Sub 9Pin) (mini 8Pin)

3 Notes for communication
Expand Serial Command is defined as a single command per line that starts with “C” and ends with
carriage return (0x0D).
There are two types of commands; Functional Execution Commands and Status Read Command.
- Example of Functional Execution Command: “CF_BRIGHT_032” [CR]
- Example of Status Read Command: “CR_BRIGHT” [CR]
Note) “_” means a space
When it takes more than a second to receive a single command, it is not executed.
When it takes more than a second to receive carriage return (0x0D) since the reception of the first
data “C”, it clears the information of the receive buffer.
When the command pipelining, allow the interval time of no less than100ms after receiving return
value. (No less than 100 ms)
Command
PC Projector “CF_BRIGHT_032” CR Next command
Projector PC “000” CR
Return Value
(A few ms - 5s)
Do not send another command before the reception of the return value; the operation by the
commond is not ensured.
However this is not the case when no response is returned after more than 5 seconds.
It takes about 5 seconds for internal initialization after plugging in AC power. During this time, it
cannot process commands. Do not issue any command.
4 Notation Convention
Data from a controller to a projector is represented as COMMAND, and data from a projector to a
controller in response to the incoming command is represented as RESPONSE.
[CR]: Carriage Return Code
Carriage Return code is added to the end of the command.
Response is also followed by carriage return code.
_: Space Code
Space Code is represented as (_).
%1: Parameter included in Command
When there are more than one parameter, they are defined as %2, %3…
%%%: Error Code returned from a projector
Acceptable: “000”.
Unacceptable: See [7. Error Code Table].
